As a result you end up with a bar low in carbs but sky high in sweeteners that will cause more havoc with insulin levels than real sugar.

Insulin is pretty simple. A set amount of insulin acts on a set amount of carbs, and thus reduces blood sugar by a set amount. Consequently, a false insulin response could result in extremely low (you are now hypoglycemic), or negative (you are now dead) blood sugar level.
Nitrox from AM summed this up pretty nicely:

Secondly, what I touched on before, is that insulin lowers blood glucose levels - always. You need a certain level of BG to maintain brain function and to keep cells alive. At rest a normal person will have about 5mmol/L of BG. Below 4 you can start to feel hypo - adrenaline being released. Heading down into the 2's there is noticeable loss of coordination. By zero the person should be unconscious and brain death would be setting in.
To illustrate quantities, take a medium banana, say 125g. That will have about 30g of carbs. Just for eating that I would take about 2 iu of insulin. Each unit of insulin is good for lowering BG about 3 mmol/L - for a total of 6. Now say I take the 2 iu but dont eat the banana: 5 minus 6 gets to zero BG - dead me. Of course adrenaline and maybe glucagon would help to prop BG up enough to barely stay alive.
So even if your body was expecting 1 iu worth of carbs with that sweet taste you would still go down into the 2's and there would be very obvious symptoms of hypoglycemia. Since there is not rampant diet soda induced hypoglycemia, IMO there are 3 possible explanations:
- The insulin level produced, if any, by a sweet taste is a statistical blip (say the amount generated by a Tic Tac).
- There have to be a large release of opposing hormones (adrenaline which would give you the shakes and/or glucagon which should counter the insulin's anabolic effect).
- Zero calorie sweeteners raise blood glucose by some unknown mechanism and cause a corresponding release of insulin.
Obviously the last two don't hold water since you would feel the adrenaline and we know that zero cal sweeteners are safe for diabetics. |

I understand people are very busy in the mornings, but a real food meal first in the day is vital. The body has been starving overnight and must have real food which provides a basis of nutrients and fiber. Without fiber your blood sugar will go haywire.

Lets take for example take nick's favorite shake: protein, banana(s), peanut butter, oats, egg whites, milk. I don't see this as any different to having porridge (milk, oats, banana(s)), a protein shake, and a couple of boiled eggs. Generalizing on the basis that it's blended is bull - that's what your digestive system would do to it anyway.

Never diet for more than 16 weeks, by that time the body is going to hold on to every bit of fat it can and chop away at muscle. You must rotate your emphasis and use phases to restore metabolism for future fat loss efforts by overfeeding to produce quality muscle which will burn more calories 24x7

In the case of a long cut, where someone may need to drop an amount of weight that exceeds 16 weeks worth of dieting, things like refeeds can prolong the diet period indefinately. For more info on that, check out this article from Avant Labs:

I agree with YG that the point regarding allergies is potentially more hassle than it is worth, but other than my previous statements, I guess I agree with most of it.
